I have been 3d printing air intakes for our m157 and m278 air intakes and I wanted to share some of the tips I've learned and really that others shared with me.
Bed Adhesion is absolutely critical to good prints. There are two parts to bed adhesion -- the first is cleaning the print bed, and the second is using a glue to lay down on the print bed. This is very important as you print bigger and hotter.
To print well for an under the hood application a printer enclosure and heater will be useful. It is also important to select the right filament. I have used ASA and PC and currently print in PC.
